I practically gave up on kit crank drives because of their poor reliability, my bbs 01 both times the controller failed having done far less miles then my hub driven bikes, then there was the GS Moon that failed again twice both controllers failed , with barely 350 miles between them.
I opted for the tsdz2 after reading and following the ES threads on them and the knowledge and easy to repair with plenty of spares etc available. Despite the so called poor rep of the drive from ES users , I opted to carry out the mods required to give better reliability on the long tail and the system has thus far proved to be good .
The crank drive with a double up front for my towing needs works well on my off road ex railway route, for other riding though it is the hub drive which is ultra reliable and without the need to bodge bits of plastic on to keep them dry or to orevent mud ingress.
